Find an equation for the perpendicular bisector of the line segment whose endpoints
are (-1, 4) and (-9, --6).

Answer 1

y = -0.8x - 5

Explanation:

x1 = (XA + XB) / 2 = -5

y1 = (YA + YB) / 2 = -1

m = (XA - XB) / (YA - YB) = -0

__________________________________________

(y - -1) = -0.8(x - -5)

y - -1 = -0.8x - 4

y = -0.8x - 4 + -1

y = -0.8x - 5
